A mysterious crewman encountered by Uhura, who was (unknown to her) the M-113 creature in Human form, spoke to her in Swahili. He stated "Ninakudhania mwanamke mzuri," which meant "I think of you, beautiful lady." (TOS: "The Man Trap")

In 2267, Uhura had her memory erased by the Nomadspaceprobe, forcing Uhura to be reeducated. While working with NurseChapel, Uhura had difficulty sounding out the words in her first grade reader, and began speaking in Swahili out of frustration, saying "Sikumbuka" ("I don't remember"). Chapel then encouraged her, by telling her to speak it in English, not Swahili, and proceeded to sound out the sentence for her. (TOS: "The Changeling")
